Specification of Letters Patent.

Patented Oct. 9 1906.

Application filed July 31, 1905. Serial No. 272.101.

To all whom it may concern:

Be it known that I, RALPH H. 'DOBBS. a citizen of the United States, residing at Seattle, in the county of King and State of Washin ton, have invented certain new and useful mprovements in Refrigerators; of which the following is a specification. My invention relates to certain new and useful improvements in refrigerators; and

claims.

erator.

In the accompanying drawings, in which like numerals of reference indicate like parts throughout the several views, Figure 1 is a view, partly in front elevation and partly in section, taken on liney y of Fig. 2', the drawers being removed. Fig. 2 is a section taken on line 2 z of Fig. 1. mentary view inperspective of one of the drawers and the adjsgcentwall of the refrig- Fig. 4 is a detail fragmentary view of one of the walls of one of the inner chambers or compartments adaptedt'o contain the articles to be preserved; and Fig. 5 is a secti'onal view of a portion of one of the walls of one of theinner chambers or compart ments, showing the roller-mountings and a portion of a drawer in elevation.

In. carrying out my invention I provide an .outer case 1, having a metallic lining l and inner chambers or compartments 2, the latter of which are formed by metallic casings spaced from the top wall of case 1 to provide a main ice-chamber 3 and spaced from each other and the side and rear walls ofcase 1 to provide vertical ice-chambers 4, 5, and 6. These last-named chambers communicate with the main ice-chamber 3, and therefore ice can be fed thereto from said main chamber and will fall and pack therein by gravity. Chambers 2 terminate or are supported at a point above the bottom of case 1, and therefore ice will fall from chambers 4, 5, and 6 to a point directl beneath the same, said ice moving beneat the lower edges thereof, and, if desired, as will be explained in the following, ice can be placed directly in the lower portions of chambers 2'through openings 7,

Fig. 3 is a detail fragformed in the front wall of case 1. Chamcured at their sides and rear walls to studding, as 8. It will thus be observed that these chambers are practically surrounded by ice-chambers, and the articles to be preserved will therefore be subjected to intense cold.

The side and end walls of the chambers 2 are formed of sections 9, which are arranged side by side in vertical alinement, and their side edges are formed with bent portions. 10,

here 2, which are open at their fronts, are se the adjacent portions of the several sections lying in proximity to each other, so as to form air-channels, which are inclined upwardly and inwardly. These channels are indicated by reference-numeral l1, and, as will be observed .by reference to Fi 1, no projecting parts result on the outer aces of these walls to obstruct the ice in its descent, and by inclining the air-channels as specified water is prevented from gaining access to the interior ofthe chambers.

Within the chambers 2 I mount means for carrying the articles to be preserved, said means preferably being in the form of drawers 12, which are slidabl'e on rollers 13, secured to the side walls of said chambers. These drawers are spaced apart. Therefore cold air can readily circulate between them,

and, further, to insure a more perfect and uni- I form cooling of the articles contained in the drawers I provide the drawers with forami nous bottoms, as 14.

The front walls of the drawers are extended downward, as at 15, b reason of which construction the front wal s of the several drawers will snugly engage one'another and entirely close the openings 7 of case 1 and prevent ingress of heat to chambers 2.

I'also preferably round one side edge of the front wall of each drawer, as at 16, so that the front walls'will more readily seat themselves in the opening 7, as is obvious. I provide the chamber 3 with a door 17, so that ice, preferably in crushed form, can be placed therein and fed into the respective chambers 4, 5, and 6, and in addition to supplying the refrigerator with ice from this point the lower drawers 12 can be readil removed and ice also placed directly into t e chambers 2 at a point below the positions normally occupied by -,said drawers. By providing the supportin means forthe drawers at the s1 rro ' es of t e chambers the interiors of, said chambers are left unobstructed and one can several functions assigned to-it. I however, that the details thereof can be readily reach into the remotest parts thereof when 'the drawers are removed, or, if the drawers are successively placed in the chambers, starting with the lower drawers, the articles to be preserved can be placed inthe drawers subsequent to their insertion in the chambers, thereby obviating necessity of first filling the drawer and theninserting the same-into the refrigerator. I preferably r0- vide the drawers with handles, as 18. En

desired type can, however, be employed, an if desired, holders,as 19, can-be attached to the drawers, the same being adapted .to receive cards bearing matter indicative of the articles contained therein. A ipe 20 car'- ries off the-water of 1i uefaction. om the ice. In the foregoing I ave described a construction which is capable of carrying out the I am aware,

readily varied without departing from: the spirit of my invention, and I therefore re serve the right to make such alterations and. changes as fall within the scope of the appended claims.

Having thus described my invention,.what I claim as new, anddesire to secure by Letters Patent of the United States of America, 1s-- I 1'. In a refrigerator, interior walls forming a chamber, said walls formed of plates arranged in vertical. line, the adjacent edges of the plates being b'enton one side thereof to form inclined air-passages therebetween.

' 2. In a refrigerator, interior walls forming a chamber, said walls formed of plates, said plates having flat walls arranged in line, the adjacent edges of the lates being bent on one side of the plate to form upwardly and inwardly inclined air-passages.

3. A refrigerator comprising an outer casing, an inner casing forming a refrigeratingchamber, said inner casing being s aced from the side Walls of the outer casing orming an ice-chamber and having its bottom open and terminating at a distance above the bottom of the outer casing forming an ice-chamber beneath said inner casing in communication with the first-named ice-chamber, means whereby ice may be; supplied to the secondnamed ice-chamber through the first-named ice-chamber, and means whereby the secondnamed ice-chamber may be supplied through the refrigerating-chamber.

In testimony whereof I affix my signature in presence of two'witnesses.
